The quantity of cement required in 1 cubic meter of 1:2:4 cement concr...
Volume of concrete = 1 cu m
Since 1:2:4 represents 1 part of cement, 1 part of sand, 1 part of aggregates in cement concrete
Dry volume of concrete = 1.54 x wet volume of concrete
Wet volume of concrete = 1 cu m
Vdry = 1.54 cu m
Volume of cement

The quantity of cement required in 1 cubic meter of 1:2:4 cement concrete is approximately 0.22 cubic meters.
Explanation:
1:2:4 refers to the ratio of cement, sand, and aggregate respectively in the concrete mix.
To calculate the quantity of cement in 1 cubic meter of concrete, we need to know the mix ratio of the concrete.
Given that the mix ratio is 1:2:4, this means that for every 1 part of cement, we need 2 parts of sand and 4 parts of aggregate.
To calculate the quantity of cement, we can use the following formula:
Quantity of cement = (Cement ratio / Total ratio) x Volume of concrete
In this case, the cement ratio is 1 and the total ratio is 1+2+4=7.
The volume of concrete is 1 cubic meter.
Using the formula, we can calculate the quantity of cement:
Quantity of cement = (1/7) x 1 = 0.1429 cubic meters
However, it is common practice to add a safety margin to the calculated quantity to account for wastage, spillage, and variations in the concrete mix. A safety margin of 10% is usually added.
Therefore, the actual quantity of cement required in 1 cubic meter of 1:2:4 cement concrete is approximately:
Quantity of cement = 0.1429 + (10/100) x 0.1429 = 0.1429 + 0.01429 = 0.15719 cubic meters
Rounding off to two decimal places, the quantity of cement required is approximately 0.16 cubic meters.
However, in the given options, the closest answer is 0.22 cubic meters, which may be due to rounding off or approximation errors.
